Definitions
- Protective layer for parts in particular a weapon, a gun carriage, a tower or the like, in particular as a corrosion protection of these parts
- the invention relates to a protective layer, in particular as corrosion protection on weapon parts, such as a machine gun, as well as parts of a carriage, a tower or the like receiving devices, in particular for a weapon that are exposed to different environmental pressures and influences.
- weapon parts of a weapon are subject not only to different mechanical requirements but also to different environmental influences.
- the problem of corrosion protection of weapon parts is currently not considered large. With the given short maintenance intervals of the weapon trying to solve this problem by cleaning and appropriate cleaning products. Accordingly, the cost of cleaning itself is very high.
- a corrosion-inhibiting color layer is often applied.
- the invention therefore has as its object to provide at least the outer weapon parts of a weapon or parts of a gun carriage, a tower or similar receptacles for a weapon with an additional corrosion protection, especially when these parts are exposed to seawater or other environmental influences.
- the invention is therefore based on the idea that parts of a weapon, etc., which are exposed to external environmental influences to provide a kind of hydrophobic and oleophobic protective layer on the surface, which in addition to a corrosion protection and a higher ServiceLERkeit the weapon causes, as these better and easier to clean.
- WO 2005/085743 A1 already proposes the use of the PVD method (physical vapor deposition method), which has already been described in EP 0 352 545 A2, EP 1 445 344 A1 or US Pat also EP 1 400 293 A1 is known.
- the plasma mist with a special nozzle and inert gas is directed so that it forms a layer on the inner wall of the bore or the barrel, which is friction, hard, temperature-resistant and wear-resistant.
- the layer consists of titanium aluminum nitride or chromium aluminum nitride.
- a corrosion protection on metals which has a layer sequence metal surface, silicon compounds containing sol layer, layer based on at least one organosilane and optionally one or more lacquer layers.
- the invention is therefore based on the idea that parts of a weapon, etc., which are exposed to external environmental influences, provided with a hydrophobic and oleophobic protective layer on the surface, in addition to a corrosion protection and a higher ServiceLERkeit the weapon causes, as these better and easier can be cleaned.
- the nano-protection can be applied to the surfaces by means of painting, dipping, powder coating, spraying etc. with a preferred layer thickness of about 1-1 ⁇ m and in the form of a clearcoat.
- polysiloxane is suitable as a nano protective layer. This ensures a hydrophobic and oleophobic surface of the treated parts. Dirt can no longer adhere to the surface of the parts. After application, the layer itself only has to cure. This is done, for example, at a temperature between 100 and 200 ° C. Can be cleaned so provided with the protective layer parts with a cleaning agent even above 50 ° C.
- nanotechnology lies in the fact that it can be used for parts intended for new construction as well as for retrofitting. Even used parts can be aftertreated with this method and re-installed in the same weapon.
- the protective layer applied with nanotechnology has been found to be suitable for parts that are not subject to abrasion in functional use. In a weapon, these were, for example, housing parts.
- a feeder 1 of a weapon not shown here an on-board cannon.
- the feeder 1 is provided on the surface 2 with a protective layer 3, which is applied in nanotechnology, a layer thickness of about 5 .mu.m.
- a protective layer 3 As the protective layer 3, polysiloxane is preferably used. At the same time, this protective layer 3 acts as corrosion protection for the surface 2.
